Glycolate accumulates in chloroplasts when there is

Glycolate accumulates in chloroplasts when there is Low CO₂.
glycolate is produced during photosynthesis as a result of a reaction between a 2-carbon piece derived from a sugar phosphate and an oxidant generated by the photochemical act.
Glycolate leads to the inhibition of metabolic processes that impair CO₂ assimilation. Furthermore, glycolate feeding to Arabidopsis roots strongly reduces root growth indicating toxic effects not related to photosynthetic processes.
